No. @8 1,1 28. Specification of Letters Patent. 'Daten'ted March 10,'f1-90S.

Application led September 16, 1907. Serial No. 393,0Me.`

To all whfm it may concern:

Be it known that l, Aeon JENSEN, a citizen of the United States,residing at Eureka, in the county of :Humboldt and State of California,have invented new and useful improvements in Liquid-Ripeners, of whichthe following is a specification.

The object of the present invention is to provide an improved form ofliquid ripener, especially adayted for ripening cream, by means of whicthe cream may be vheated to the desired temperature and maintained atsuch temperature long as may be necessary lwith great uniformitythroughout the entire body of the liquid; or by which a liquid may beuniformly cooled if desired.

In the accompanying drawing, Figure 1 is a broken side elevation of themachine; Fig.. 2 is an end view thereof; F ig. 3 is a cross, sec

broken vertical sectional view, and Fig. 5 is a broken inside view,showin'gthe connection of the bearing to the metallic lining.

Referring tothe drawing, V1 indicates the legs Said casing issemicylindrical in its lower portion having the u per portions of thesides flat, and downwar ly sloping lids 3, one on each side, which lidsare secured by cam fastenings e, and make an air-tight Each end of thecasing is centrally apertured, and within each aperture is a closetltinghearing? for a hollow shaft 8, there being secured upon the innerend of each shaft a hub 9 formed upon the corresponding head 1050i arevoluble hollow agitator 11. Each such head 10 is in the form of twohollow radial arms extending in opposite directions from the hub, andthe agitator comprises, in addition to the two hollow heads 10, thelongitudinal tubes 12 connecting said heads.y vSaid tubes are preferablyin cross section of the form of an ellipse having sharp ends,.as moreclearly shown in Eig. 3. It is nishes a maximum amount of heating orcooling surface while at. the same time the friction of the agitator inmoving through the liquid, and therefore the power necessary to give ita given speed, is reduced to a minimum. One-half of the head or radialarm at one end of the machine, and the other half at the, other endthereof extending in` the opposite direction from the first half, areformed in the vinterior with longitudinal partitions 13,

leading fromgthe hub to the outer ends of said heads.' Each suchone-halfof the head is thereby divided longitudinally into cornpartments, ofwhichthe outer compartment constitutes achannel la leading to theoutermost tube 12, while the,inner compartment is again divided bytransverse partitions 15 extending from one side of the llongitudinalpartition 13, .into conduitsy 16, each connect' ing the ends of twovadjacent .longitudinal tubes 12. The other halves ofthe heads or radialarmshave l.no longitudinal partition,

but have, each of them, transverse partitions 17, dividing the interiorofsaid arms into conduits 18, each also connected with the ends of -twolongitudinal tubes 12.. The

transverse partitions .at the opposite ends of the machine are soarranged that the longitudinal tubes, and the .conduits connecting them.in airs, form a zigzag or ytortuous conduits or the heating orcoolingmedium.

The two hubs 9 are'both secured to `a ceny tral tube 19.,which servesmerely to strengthen the apparatus, there being placed in each endthereof a block 20 which arrests the passage of the heating or coolingfluid along said tube, and compels said fluid into or out `of thev abovedescribed tortuous conduits, which itv does by passage 21 in the wallsof said tube;

It will be understood that, by the above arrangement, the heating orcoolingfluid admitted to the hollow shaft at one end of the machineflows therefrom by said openings21 in two opposite directions. One partenters that half of the head which is dividedby the longitudinalpartition 13, and lconsequently vcircuitous path through said tubes inSuccesy sion to the outermost tube 12, then owng along thelongitudinally divided hollow arm at the other end of the machine. It'.thus givs up its heat or cold first tothe surrounding liquid in thecentral part of the bhainber of the machine, and. then in'succession toparts thereof farther outwards. Each of saidshafts 8 passing through thebearing 7&5

.provided with a stuffing box 24,`and connects at its outer end with apipe for conductin the heating or cooling fluid. At one end sai hollowshaft 8 connects -with a pipe25, and

at the other end the hollow shaft. connects with a pipe 26, theconnectionwith each pipe being made liquid tight by means of a stuifingbox 27 having a screw collar 28. One of said shafts has secured-thereona worm wheel.

29 which is driven by a Worm 30 on a shaft 31 carry-ing tight and loose'pulleys 32, 33 -by whichthe bshaft may be driven from-,any

source of power..` .By this means a slow zle 40 from a steam pipe 41controlled by a valve 42. lf it is desired to use cold water or brinethe valve 42 is closed so that no steam can enter. The pipe 38 is alsoconnected with a pipe 43 leading from the otherend of" the machine andhaving -therein a check valve 44 the other end of said-.pipe 43 beinglconnected with apipe 45 which is connected' with the pipe .26 leadingfrom the other hollow shaft. Y 'lhe pipes 26, 45, 43, 38, and 25 thusform with the hollow 'agitator a complete fluid circuit, the check valve44 allowing the fluid to flow only in the direction indicated by thearrow. The pipe 45 is extended upwards and carries an overflow vessel 47open at the top and having a discharge pipe 48 at the side. The objectof providing this overflow vessel is to insure that the pressure in thelagitator is uniform and of any desired magnitude, depending upon theheight of the overflow The liquid from the casing is drained by anoutlet 52 being closed by a gate valve 53. v With an apparatus of thischaracter, when it is desired to supply a heated liquid to the agitator,the valve 42;v is 0 ened to admit steam to the nozzle 40, t erebycreating a suction'in the direction of the arrow and at Athe same timeheating the liquid, causing the heated liquid to flow in the directionof the arrows 'through the agitator and when discharged therefrom toreturn by the pipes 45, 43, 3 8, the operation ol' the apparatus beingnoiseless.

It will now be understood why it is desirableto divide' the heating orcooling current intoI two streams which flow respectively to the .innerand outer portions oft'he chamber ofthe-machine. Sincethe agitator iscontinuusly rotating, the effect ofzfsupplying these'ltwov streams, theone lowingto the middle part ofthe chamber and thence outwards,

andthe ptherflotving tothe outer part of the cha-inbeiz and thenceinwards, is to cause the -jabstraction of heat or cold from the agitatorto be `uniform at all points of the ch:A nber. This is of' greatimportance vin anyripening process where a slight variation oftemperature is' ofimportance in affecting the success of the processorthe character of the product.

4In using this machine, the receptacle for the liquid is filled to anydesired height, but inasmuch as in any case there is a considerablespace intervening vbetween'the level of the top of the liquid and thetop of the casing, the liquid cannot be rotated bodily with theagitator. The result is that no rotation can v be imparted to the liquidas a whole, and in consequence fresh surfaces of the liquid arecontinuously exposed to the heating and cooling effect of the agitator.'Moreover, since at all times a`portion of the agitator is rising out ofcontact with theliquid, said agitator more readily carries 'with itfromvthe liquid gases or products of fermentation which might bedetrimental to the product.

ln order to insure a sanitary joint between the revolving andstationaryportions of fthe apparatus there is securedv u on the outside o eachhead of the casing a p atel 51 throu h whichsare :screwed adjustingscrews 54 t e Ainner ends ofv which bear against the outer entl of thebearing 7, and press the inner end of said bearing against the vadjacentsurface of the corresponding hub, thereby making a perfectly tight jointbetween said surfaces.

The above construction'provides a bearing which is of a sanitarycharacter, since the adjustment of the bearingcan be made from theoutside by means of said screws. the stufling boxes at the outer ends ofthe bearings are entirely disconnected with the interior of thereceptacle. The stui'ling boxes are all readily accessible and canalways be made perfectly tight to revent the passage therethrough of anyfluir The interior of the, casing is lined with a lining 55 of copper orother metal which does not injuriously affect the liquid being treated.The bearing is formed with a circular lll() flange 56 which is securedby rivets 57 or*4 ,by this adjustment the end ofthe bearing is movedinto close contact withthe end `of the' hub, it will readily be seenthat thisarrangement provides an absolutely ti ht jointto prevent thepassage of liquid eit er between the bearing and the hub or between thebearing and the wall of the receptacle.
